Detailed description of the invention
Core of the present invention is for providing a kind of stretching device of hollow-fibre membrane, and the stretching device of this hollow-fibre membrane, by its structural design, can improve the product quality of tunica fibrosa.
In order to make those skilled in the art understand technical scheme of the present invention better, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Please refer to Fig. 1, Fig. 1 is the stretching device of hollow-fibre membrane and the structural representation of sizing in an embodiment of the present invention.
The invention provides a kind of stretching device of hollow-fibre membrane, for stretching to tunica fibrosa, making the fineness of film silk more consistent by stretching to film silk, thus improve the product quality of hollow-fibre membrane.
The stretching device of hollow-fibre membrane provided by the invention comprises: tension roll assembly, tension roll assembly comprises one-level higher level roller 5 and one-level lower roller 4, hollow-fibre membrane is S-type to be wound between one-level higher level roller 5 and one-level lower roller 4, and drawing zone is provided with divided section heater, for stretching of heating; Styling components 9, styling components 9 comprises the heater for heating hollow-fibre membrane, and the tension roll assembly being no less than two groups is arranged on styling components 9, and secondary higher level's roller 6 and lower roller 7 are relatively arranged on the both sides of styling components 9, are arranged vertically; Put roll dies 1, put the front end that roll dies 1 is arranged at tension roll assembly; Wind-up roll 8, wind-up roll 8 is arranged at the rear end of tension roll assembly, and rolling speed is consistent with shaping area jockey pulley; Pressure roller 2, has the gap passed for hollow-fibre membrane between pressure roller 2 and elementary higher level's roller 3.
In said structure design, acting as of tension roll assembly applies pulling force to the tunica fibrosa be wound in one-level higher level roller 5 and one-level lower roller 4.One-level higher level roller 5 and one-level lower roller 4 interval are arranged, and tunica fibrosa is S-type to be wound on two rollers.The number of tension roll assembly is provided with multiple, and tunica fibrosa like this is roundabout to be arranged on whole tension roll assembly, by adjusting the rotating speed between each roller, forming speed ratio, reaching the object of tunica fibrosa stretching pore-forming, so raise the efficiency the quality with product.
Put the two ends that roll dies 1 and wind-up roll 8 are arranged at tension roll assembly respectively, put silk and rolling for carrying out, drawing zone completes the continued extension to tunica fibrosa at this process tension roll assembly, and shaping area completes the film silk sizing to stretching out.
Pressure roller 2 and higher level's roller 3 interval are arranged, and tunica fibrosa is arranged between pressure roller 2 and elementary higher level's roller 3, by adjusting the press power of pressure roller 2, can ensure that tunica fibrosa enters thread tension consistent, also can change pressure roller 2 into tensometer and can achieve the goal equally.Meanwhile, by the structural design of tension roll assembly, ensure that tunica fibrosa is subject to the uniformity of tensile force in drawing process, high degree like this improves the product quality after tunica fibrosa stretching.
Styling components 9 is the platforms for providing heating when tunica fibrosa stretches, and comprises heater, can after tunica fibrosa has stretched timely heat-shaping, then by identical tension constant speed auto reeling receive silk.
The stretching device of hollow-fibre membrane provided by the invention, by the structural design that it is special, can effectively carry out continuously elongated to hollow fiber film thread, due to the even tension that is subject to of tunica fibrosa when stretching, make film silk wall thickness and pore-forming evenly.
The continuously elongated principle of hollow-fibre membrane is: carry out continuous free of discontinuities stretching by tension roll assembly to film silk.
It should be noted that, between one-level higher level roller 5 and one-level lower roller 4, there is speed discrepancy, owing to there is this speed discrepancy, can make to be wound in one-level higher level roller 5 and produce tension force with the tunica fibrosa in one-level lower roller 4, also can subregion different temperatures stretch simultaneously.
Initially put silk place at hollow-fibre membrane, adopt pressure roller 2 to control the size of a power of putting; The velocity of rotation of adjustment one-level higher level roller 5 or one-level lower roller 4, for adjusting into a speed, entering a Speed Setting is 0.1m/min to 10m/min; Partition heating, overall heating or one section of cold drawn one section of hot-drawn can be selected by thermal baffle according to tunica fibrosa technological requirement; By sizing after stretching completes, last tunica fibrosa completes rolling by wind-up roll 8.
In the present invention, mode of heating has: wind-heat, heating water bath, oil bath roller, electric heating roller.The tension roll assembly that styling components 9 both sides are installed has driven the tunica fibrosa of stretching to enter shaping area, and the setting temperature that styling components 9 provides is higher, is about 80 DEG C to 160 DEG C, and shaping time is 10 minutes to 100 minutes.
Not only can complete hollow-fibre membrane stretching pore-forming by this continuously elongated technique and device, and hollow-fibre membrane stretch after wall thickness and pore-forming evenly, continuously, uninterrupted, finished product rolling, is convenient to the techniques such as follow-up braiding processing.
The stretching device tool of hollow-fibre membrane provided by the invention has the following advantages:
1, carry out continuously elongated by the differential between one-level higher level roller 5 and one-level lower roller 4 to film silk, do not need to be interrupted, reach continuous seepage;
2, hollow-fibre membrane puts silk place, adopts pressure roller 2 to control the size of a power of putting, ensures into silk place hollow-fibre membrane even tension;
3, the one-level higher level roller 5 in tension roll assembly and one-level lower roller 4, respectively by Serve Motor Control, draw zone carry out partition heating stretching, and it is processed, mode of heating is flexible;
4, tension roll assembly setting quantity is comparatively random, infinitely can increase, can realize up to a hundred tunica fibrosa silks and stretch simultaneously, improve production efficiency dramatically according to actual production;
Particularly, whole tension roll assembly drives running by pinion unit by power set.
Particularly, in whole tension roll assembly, each one-level higher level roller 5 and each one-level lower roller 4 are provided with independently drive unit and drive it to operate.In the present embodiment, because each roller is driven by independently drive unit, be convenient to the rotating speed adjusting one-level higher level roller 5 or one-level lower roller 4.
